Yews are popular evergreen shrubs that add beauty and structure to gardens. However, they can struggle due to poor soil conditions, improper watering, or nutrient deficiencies. Proper fertilization can help revive struggling yews and promote healthy growth.
Understanding Yew Nutritional Needs
Yews prefer well-drained, slightly acidic to neutral soil. They require essential nutrients such as nitrogen, phosphorus, and potassium, along with trace minerals like iron and magnesium. Recognizing signs of nutrient deficiency is key to effective fertilization.
Signs of Nutrient Deficiency
- Yellowing leaves, especially on new growth (indicates nitrogen deficiency)
- Poor growth or stunted size
- Fading or pale foliage (possible iron deficiency)
- Branch dieback
Choosing the Right Fertilizer
Select a balanced, slow-release fertilizer formulated for evergreen shrubs. Look for products with an N-P-K ratio such as 10-8-10 or similar. Incorporate trace minerals if deficiencies are suspected.
Organic vs. Synthetic Fertilizers
Organic fertilizers, like composted manure or fish emulsion, improve soil health over time and are environmentally friendly. Synthetic fertilizers provide quick nutrient availability but should be used carefully to avoid overfeeding.
Applying Fertilizer Properly
Apply fertilizer in early spring before new growth begins. Follow package instructions for dosage. Spread the fertilizer evenly around the base of the yew, avoiding direct contact with the trunk.
Water thoroughly after application to help nutrients penetrate the soil. Repeat fertilization once or twice during the growing season, depending on the product and plant response.
Additional Care Tips
- Ensure proper watering—keep soil moist but not waterlogged
- Mulch around the base to retain moisture and regulate soil temperature
- Prune dead or damaged branches to stimulate healthy growth
- Test soil pH and amend if necessary to optimize nutrient uptake
Monitoring and Adjusting Fertilization
Observe your yew for signs of improvement, such as new growth and lush foliage. Adjust fertilization schedule based on plant response and soil conditions. Consistent care will help your yew recover and thrive.
Reviving struggling yews requires patience and proper nutrition. With the right fertilization practices, you can restore your yew’s health and enjoy its beauty for years to come.
